Implementation of Obstruction Avoiding Robot using Ultrasonic Sensor and Arduino UNO

Abstract

This project attempts to create an obstruction avoiding robot which can automatically sense the presence of an obstruction in its path and avoid them. It intelligently detects barrier present in its path through the ultrasonic sensors, with the help of the internal code from the Arduino UNO, decisions are made to avoid the barriers. This has been achieved by using an ultrasonic sensor and the development board Arduino UNO. The ultrasonic sensor is mounted on a servo motor at the front of the vehicle for a wider field of view. The ultrasonic sensor acquires data which is processed by the Arduino which then decides the direction of travel for the robot. The robot requires low voltage and minimal maintenance for continued operation. Arduino being an open-source software has gained popularity for the creation of basic prototypes due to its relative simplicity in both design and coding. It also boasts of a large online community of learners and engineers.
